TO PASS
What is the fundamental principle of all biology? Correct answer-Evolution
Forces observed today act the same way as they did in the past Correct answer-Uniformitarianism
Younger rocks deposited above older rocks Correct answer-Superposition
The picking out of individuals with any desired quality and breeding from them Correct answer-
Artificial selection
What is the primary mechanism of evolutionary change? Correct answer-Natural selection
1) more individuals are born that can survive/reproduce 2) Individuals vary in most traits
3)Individuals with certain traits are more likely to survive and reproduce 4) Variation is at least partly
heritable Correct answer-Natural selection 4 hypotheses
Structures change over an individuals lifetime and pass on those acquired characters to descendants
- INCORRECT Correct answer-Lamarkian evolution
Inheritance of pre-existing characters, change over generations in the proportion of individuals in a
population that possess a heritable trait Correct answer-Darwinian evolution
